Asample of an ideal gas (5.00 l) in a closed container at 28.0°c and 95.0 torr is heated to 290 °c. the pressure of the gas at this temperature is torr. о 178 ооо о 50.8

178 torr

Explanation:

Using Ideal gas equation for same mole of gas as

Given ,  

V₁ = 5 mL

V₂ = 5 mL (Closed container)

P₁ = 95.0 torr

P₂ = ?

T₁ = 28.0 ºC

T₂ = 290 ºC

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T₁ = (28 + 273.15) K = 301.15 K  

T₂ = (290 + 273.15) K = 563.15 K  

Using above equation as:

Solving for V₂ , we get:

P₂ = 178 torr

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

the answer is c.the valence of the atoms combine .
